..and the Lord has spoketh'
Yeah, the limitations are there, but it would be great addition to a slower paced games for example a moving colorful background or static background. There are a lot of static games like chess, which could use backgrounds, maybe even changeable one's by the press of an option button. Some cool photos of girls and stuff in background should liven up the game play and make the game more interesting and popular. For example, some QIX clone like game could sure use some "more interesting" pictures for people to uncover during the game If you know what I mean..
Sometimes it takes something subtle to make all the difference in a game..
Just a thought for homebrew developers/artists
